So there were a few combinations that didn't work when I did them. I play the PS4 version, Enhanced Edition.
Adding a pearl to armor didn't increase its value Adding metal scraps to cloth armor didn't improve it Arrowhead + debuff potion (didn't try all of them yet) didn't result in the new arrow-type arrowhead golden grail + armor didn't increase value, only changed the color
Is there a way to craft trap disarm kits? I've found tongs, which look exactly the same to the trap disarm kits. I've tried a number of combinations with the tongs, and not anything has worked yet.
Can shells be used in any combination?
Is there something that adds Loremaster point(s) to an item? I think it's only on rings and amulets that I've bought or found.
